Shanties

Shanties are tunes sung by Edward's crew while sailing. There are a total of 34 of them that can be found in major and minor locations around the map (they are marked as music symbols). These shanties act like almanac pages in Assassin's Creed III. Chase them down and collect them.

Note that shanties will appear again after a brief period if you miss them and will fly away along the same path each time. You can use this to your advantage if you're having problems catching one. Simply trigger the page to fly away, then wait in the location it first appeared in. It'll reappear and you can collect it very easily.
